19.4: Using the Parity-Check Matrix For Decoding

WebIn coding theory, Hamming (7,4) is a linear error-correcting code that encodes four bits of data into seven bits by adding three parity bits. It is a member of a larger family of Hamming codes, but the term Hamming code often refers to this specific code that Richard W. Hamming introduced in 1950. WebNov 30, 2024 · Thus each possible code can be determined using its length n (number of bits in a code word) or its rank k (number of data bits in a code word). A Hamming code can be referred to as (n, k), e.g., (7, 4) or (40, 34). Each code has a generator matrix, a binary matrix with which an input vector can be multiplied to obtain a code word.

WebJun 6, 2024 · The Binary Hamming code Using the idea of creating parity bits with the XOR operator, we can create what is called the Hamming [7, 4] -code. We will combine multiple bits to create each of the parity bits for this code. This code will take in a four-bit input and encode it into a seven-bit codeword. WebHamming codes are distance-3 linear block codes, so they can be used for single error correction (SEC) or dual error detection (DED). For binary Hamming codes, the codeword length is given by Equation 14.9, the number of parity bits is r, and the number of message bits is therefore given by Equation 14.10. (14.9) (14.10)
